Digital copyright confirmation method and system based on alliance chain

Abstract

The invention discloses a digital copyright confirmation method and system based on an alliance chain, and the method comprises the steps: 1, receiving a copyright to-be-authenticated file and a copyright authentication application submitted by a user, generating an examination intelligent contract, and sending the copyright to-be-authenticated file to a copyright reviewer; 2, receiving copyrightconfirmation information submitted by a copyright reviewer, and reviewing information sent by the smart contract to the user; 3, extracting the transaction record and the review intelligent contract formed in the steps 1 and 2, sending to a to-be-confirmed resource pool; 4, an alliance main node of the alliance chain network constructing a new block for the to-be-confirmed resource pool, and broadcasting the new block to the whole network; and 5, performing consensus verification on the new block in the whole network, and if the consensus verification is passed, adding the new block into the digital copyright block chain to complete copyright registration of the copyright to-be-authenticated file. According to the invention, the copyright registration operation of the user is simplified, the copyright registration cost is reduced, the copyright registration efficiency is improved, and the security is high.

Description

technical field [0001] The present invention relates to the technical field of digital rights protection (Digital Right Management, DRM), in particular to a digital rights confirmation method and system based on alliance chain. Background technique [0002] With the rapid development of the Internet, the online literature industry is also booming. Internet technology makes content production and output more timely and efficient, and has the characteristics of fast and efficient dissemination without space constraints, which facilitates people's reading. However, the characteristics of easy duplication and modification of digital works have caused the proliferation of online piracy and seriously hindered the healthy development of the online literature industry. At the same time, the speed of traditional copyright registration is much slower than the production speed of original works, and it is expensive, which further reduces the willingness of creators to register copyrig...

Problems solved by technology

Although the blockchain technology has many advantages, if it is directly used in the digital copyright registration system, there will be some problems: First, the use of the public chain architecture ensures the stable operation of the system and the security of the data through the participation of a large number of public nodes and reliability, but the participation of a large number of nodes will cause a waste of resources; secondly, the workload proof mechanism (Proof of Work, POW) is used to solve the consensus problem in the public chain, but the working principle of POW depends on a large number of calculations, which will cause a large number of calculations. The waste of power, and the speed is slow, and the throughput is relatively low; again, all nodes have all the ledgers, and the data is completely open and transparent to all nodes, so it cannot meet the requirements of privacy protection; finally, without relying on the central organization, It completely relies on the consensus mechanism among all nodes to record data. Any independent node or a small set of nodes cannot control the data records of this network. While this mechanism reduces the possibility of malicious nodes or attacks, it also cannot The stored data is effectively supervised
